1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2  5476 (Continuum Snapshots of 3CR Radio Galaxies) 

       The WF/PC-2 was used to make snapshot images of radio galaxy 3C169.0
       as part of a continuum survey and to study the galaxy's morphology.
       The observations were executed as scheduled, and no anomalies were
       noted. 

   1.2 Completed WF/PC-2 5764 (WF/PC-2 Cycle 4 Calibration: Internal Flats 
       - Repeat)

       The WF/PC-2 was used to make internal flat calibration images using
       the VIS lamp and internal sources. The observations were executed as
       scheduled, and no anomalies were noted. 

   1.3 Completed FGS 5316 (Masses of Pre-Main Sequence Stars: Cycle 4 
       Medium)

       The Fine Guidance Sensors were used in the TRANS Mode to make
       astrometric observations of the pre-main sequence binary star ZZ-Tau
       in the Taurus star forming region. The FGS data will provide the
       apparent orbits. The observations were executed as scheduled, and no
       anomalies were noted. 

   1.4 Completed WF/PC-2 5370 (HST Medium-Deep Survey: Cycle 4 High, High 
       Galactic Latitude)

       The WF/PC-2 was used in parallel with the prime science observations
       to make high galactic latitude observations as part of a medium-deep
       sky survey. The observations were completed as planned, and no
       problems were reported. 

   1.5 Completed GHRS/2 5769 (UV Spectroimaging of Saturn and Search for 
       Exogenous Water in the Atmosphere)

       The High Resolution Spectrograph (Side Two) was used to make
       ultraviolet spectrographic observations of the North and South
       Hemispheres of the Planet Saturn to look for exogenous water. The
       target acquisition was performed on the moon Mimus, followed by
       offsets to several regions on Saturn. The observations were executed
       as scheduled, and no anomalies were noted. 

   1.6 Completed Three Sets of FOC/96 5705 (A Color-Magnitude Array of
       NGC-7099: Cycle 4 Carry-over) 

       The Faint Object Camera (f/96) was used to make a series of
       observations of the globular cluster NGC-7099 in two bands which will
       be used to build a color-magnitude array. Observations were made at
       the core of the cluster, and at offsets from the core. The
       observations were completed as planned, and no problems were reported 

   1.7 Completed Three Sets of WF/PC-2 5571 (WF/PC-2 Cycle 4 Calibration:
       Earthflats, Smaller Set) 

       The WF/PC-2 was used to make several ultraviolet and narrow-band
       filter Earth flat calibration observations to correct for the
       telescope's illumination pattern. The observations were completed as
       planned, and no problems were reported. 

   1.8 Completed WF/PC-2 5479 (Subarcsecond Structure in Nearby AGNs)

       The WF/PC-2 was used to make snapshot observations of the nearby
       active galactic nuclei of NGC-6211 to study the interactions between
       the central engine, the stars, and the interstellar matter in the
       AGN. The observations were executed as scheduled, and no anomalies
       were noted. 

   1.9 Completed WF/PC-2 5397 (Determination of the Extragalactic Distance 
       Scale: Cycle 4 High)

       The WF/PC-2 was used to make images of galaxy NGC-3351 to be used in
       measuring the periods of Cepheid variable stars within the galaxy.
       The observations were completed as planned, and no anomalies were
       noted. 

   1.10 Completed FOS/RD 5535 (Cycle 4 Internal Wavelength Calibration)

       The Faint Object Spectrograph was used to make internal calibration
       observations to monitor the stability of the wavelength scale for
       different gratings. The observations were completed as planned, and
       no problems were reported. 

2.0 FLIGHT OPERATIONS SUMMARY:

   2.1 Guide Star Acquisitions: 

                            Scheduled Acquisitions : 7
                                        Successful : 7

                          Scheduled Reacquisitions : 7
                                        Successful : 7

   2.2 FHST Updates: 

                              Scheduled : 17
                             Successful : 17

   2.3 Significant HSTARs: None

   2.4 Operations Notes: 

       Initial STGT operations continued with the introduction of the East
       Satellite.  There was only one TTR filed -- for a 2 minute, 55
       second recoverable 32k data loss due to a problem with the
       integrated receiver. 

       The Gyro #5 motor current transition from a nominal 98 mA to 156.8
       mA had a signature very similar to the original Gyro #5 failure,
       with the exception that a current spike was not previously observed.
       Operational limits have been adjusted, and Gyro #5 data is being
       closely monitored. Operations were maintained, and there was no 
       impact to science observations. 

3.0 ANOMALY STATUS:

   3.1 Significant New Anomalies: None

   3.2 Significant Unresolved Anomalies: None

4.0 SIGNIFICANT FORTHCOMING EVENTS: 

        Nothing at this time.
